So I did:
diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig
index 5ed9cbf378f..61192fb4a43 100644
--- a/arch/arm/Kconfig
+++ b/arch/arm/Kconfig

select BOARD_LATE_INIT

- select LINUX_KERNEL_IMAGE_HEADER
imply CMD_DM
config ARCH_SOCFPGA
But it didn't help.

I see you have still preserved arch/arm/dts/dragonboard410c.dts with
memory layout. I switched to it via:
diff --git a/configs/dragonboard410c_defconfig
b/configs/dragonboard410c_defconfig

But that didn't help it to boot, still no U-Boot console log.

The driver model isn't available for DEBUG_UART, so it can directly
invoke msm_uart_clk_init().

I can help keep digging in but since this series overhauls db410c
support I expected it to be at least tested.
